Title: Beam alignment device for a particle beam
IPC: H01J37/147
Filed: 1971-08-24
Abstract: 1367940 Electron beam. deflection systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 24 Aug 1971 [27 Aug 1970] 39626/71 Heading H1D A beam alignment device arranged to align a beam of charged particles (e.g. electrons or ions, and as in an electron microscope for example), with a system axis, comprises two composite deflection systems (12, 13), Fig. 1 (not shown), forming four double deflection systems, the respective deflection planes A, B being spaced apart, and each composite system being arranged to deflect the beam in two mutually orthogonal directions, and alignment control members to control effective angular displacements of the beam about respective displacement axes in respective ones of two adjustment planes (e.g. a plane containing source 30 and a plane containing aperture 32, or object (8) (Fig. 1, not shown), there being one control member only for each effective angular displacement and to cause the composite deflection systems to deflect the beam in opposite transverse directions respectively parallel to the two axial planes, and to cause the ratio of the corresponding deflection angles (e.g. α 1 /α 2  and # 1 /# 2 ) to be substantially the inverse of the ratio of the distances of the respective deflection planes from the corresponding adjustment planes. Alignment for one axial plane is described with reference to Fig. 3. The beam is angularly displaced about an axis in a first adjustment plane containing source 30, and about an axis in a second adjustment plane containing aperture 32 to effect complete alignment with the axis. Preferably the deflection systems are formed by e.m. coils proportioned in geometry and number of turns that a common energizing current ensures conformity of deflection angles to the required ratio. Trimming resistors may provide exact adjustment. Fig. 1 (not shown) includes in an electron microscope, anode (4), condenser (5), diaphragm (6) (which may alternatively be in front of, or in the condenser), objective (7), projector (9) and image screen (10) preferably forming part of the envelope (11). Deflection system (12) comprises coils (14), (15), (16), (17) with corresponding coils on the other side of the axis (Fig. 2, not shown), and second system (13), comprises four similar double system coils (18, 19, 20, 21) Coil mounting Al block (23) is in epoxy resin casting (24). Alignment of the beam is by current control in coils (14), (18) for example of one alignment system and correspondingly for the other systems. The deflection elements may alternatively be electrostatic plates or adjustable permanent magnets. Reference is made to Specification 1,193,250.

Title: Improved stretch yarns and methods and apparatus for making the same
IPC: D02G1/10
Filed: 1956-12-31
Abstract: 850,286. Crimping yarns; yarn guides. DEERING MILLIKEN RESEARCH CORPORATION. Dec. 31, 1956 (Dec. 30, 1955], No. 39654/56. Classes 120(2) and 120(3). In a process for crimping or converting monofilament yarn of "circular" cross-section into a stretch yarn by passing a running length of the yarn under tension through a path having an acutely angular portion, the yarn is at least partially confined so that it is forced to retain its cross-sectional form i.e. not more than 15 % of the surface is flattened so that it has a radius of curvature greater than the mean radius of the yarn and the minimum diameter of the yarn is  at least 80% of the maximum thereof. As shown in Fig. 1, yarn 12 is led from a package 10, through a guide 14, about a tension regulator 16, to a blade assembly 18 which comprises an arcuate electrically heated strip 28 mounting, in a holder 40, a flat plate of durable material such as stainless or high-carbon steel, diamond or sapphire constituting a blade 42 one edge of which has a yarn-confining notch 46 positioned at the apex of an angular path formed by the yarn passing in contact with the under side of the strip and through the notch. Yarn is withdrawn from the blade at 20 by driven rolls 24 and taken up by ring-and-spindle array 26. The minimum radius of curvature of the acutely angular portion of the path is not more than four times the (predetermined) diameter of the yarn. As shown in Figs. 2 and 3, the rear boundary 48 of the notch is concavely curved in the plane of the blade with the mean radius of curvature approximating the yarn radius and is also concavely arcuate in other planes at the apex so that the yarn is confined during most of its passage through the angular portion: boundary 48 is also convexly curved in planes perpendicular to the plane of the blade with the radius of such curvature a minimum in the centre of the boundary surface and approaching infinity where the curved rear boundary surfaces of the notch join the plane side surfaces. Plate 42 also comprises grooves 50, 52 forming yarn guideways to and from the base of the notch and assisting in confining the yarn to circular cross-section. Guides, as at 50, 52, are unnecessary if the plate is sufficiently thin to enable the base of a notch to provide an acceptable minimum radius of curvature, Fig. 5 (not shown). Yarn, immediately following its passage about the blade and dependant on whether it is untensioned or torsionally stressed, may have portions equally coiled in opposite directions with reversal points randomly spaced along the length of the yarn, or form coils running in the same direction. Stretch properties are fully developed by thermal relaxation.

Title: Improvements in or relating to printing cylinders and mandrels
IPC: B41F13/10
Filed: 1956-12-31
Abstract: 824,380. Making printing rollers; jointing. MOSSTYPE ROLLER CO. Inc. Dec. 31, 1956, No. 39662/56. Classes 83 (2) and 83 (4). [Also in Group VIII] A printing cylinder comprises a tubular member 12, Fig. 7, having end closures 13 with bores 14 of a diameter slightly less than that of a mandrel 11 whereby the end closures may be thermally expanded for assembling or disassembling the cylinder and mandrel. The end closures may be formed integrally with the member 12 or be secured to it by welding and may be of magnesium or other material having a higher coefficient of thermal expansion than the mandrel. Heat may be applied by an annular electrical heating unit 15 held against the end closures by a clamp 16. In Fig. 6, the end closures 69 are counterbored at 67 to reduce the area of contact with the mandrel and the heating unit 71 is removably mounted on an extension of the end closure. The cylinder is in two parts keyed together at 75 and each part includes a plug 64 having a sliding fit on the mandrel. End closures similar to those shown at 69 may be formed integrally with the cylinder 12. The latter may have an annular recess in each end closure to receive the heating unit. Alternatively, it may have end portions with an increased internal diameter to receive the end closures, a heating unit being accommodated in a peripheral groove in each end closure or being interposed between the closure and the corresponding internal shoulder of the cylinder. In Fig. 8, the end closures have tapered bores to co-operate with tapered shoulders 87, 88 which have annular grooves to reduce the heat transmitted to the mandrel. Fig. 11 shows a heating unit 113 mounted in a thermal insulator 112 carried by a cup-like member 106 which has arcuate tabs to be passed through axial grooves in the cylinder to engage arcuate grooves 104. Collars secured by set screws to the mandrel and having pins to engage recesses in the end closure may be used to ensure correct location of the cylinders. In a further construction, the mandrel is hollow so that a cooling fluid may be passed through it.

Title: Capping machine for containers
IPC: B65B7/28
Filed: 1929-12-30
Abstract: 344,978. Apparatus for applying disc closures. ROGERS, F. H., 181, Queen Victoria Street, London.-(Vortex Mfg. Co. ; 421, North Western Avenue, Chicago, U.S.A.) Dec. 30, 1929, No. 39803. [Class 125 (ii).] A machine for capping paper or like containers comprises a rotary table or support adapted to receive the containers after they have been filled with ice cream or the like and fitted with paper or like caps, a reciprocating rim-crimping mechanism adapted to deflect the rim of a container and crimp it over the cap, and pedal or manually operated means adapted at each operation, first, to impart rotation to the table for the purpose of bringing a container beneath the crimping head, and then to actuate the crimping mechanism. A rotary table 24, provided with a plurality of sockets 26, is mounted on a shaft 16, Fig. 1, having a ratchet wheel 17 adapted to be actuated by means of a pawl 18 supported by a crank arm 19, the latter being operatively connected with a foot treadle 7 by means of a rod 21, bell crank 22, and a spring- controlled rod 8. An arm 40, pivoted on a pin 41 and positioned in coacting engagement with the long arm of the bell crank 22, is connected by means of a pin 38 with a spring-controlled centring bolt 34, Fig. 2, slidably mounted on the frame 13 and provided with a tooth 35 for engagement with notches 25 in the table. The crimping mechanism comprises a plunger rod 41a slidably mounted in a support 42 and pivotally connected to a fulcrumed beam 48, the rear end of which is connected to the foot treadle by means of a spring-controlled rod 53. A plate 58, Fig. 3, is attached to the lower end of the plunger rod 41a by a screw 59, carries a pair of posts 60, on the lower ends of which is rigidly secured a crimping head or die 61 having a recess 62 to receive a cap-retaining plunger 63 which is mounted on the deflecting cap or hood 66 by means of a screw 65. A spring 67, positioned between the plate 58 and the cap 66 and engaged around the heads of the screws 59, 65, holds the deflecting cap resiliently against the top of the crimping die. In operation, when the treadle 7 is first depressed, it pivots about the lower end of the rod 53, during which time the table is rotated and the centring bolt 34 is released to engage one of the notches 25. Subsequent pressure on the treadle causes the fulcrum point to be transferred to a pin 6, which at this stage rests at the bottom of a slot 5, with the result that the rod 53 is raised and the plunger 41a is actuated to lower the deflecting cap 63 and deflect the rim of the container. The downward movement of the deflection cap however is limited by a shoulder 28 on the table and the plunger, during the remainder of its stroke, is caused to act on the plate 58 which compresses the spring 65 and pushes down the crimping head 61 to complete the closure. Release of the treadle permits the return of all the parts to normal position.

[Also in Division D1] The disclosure includes substantially the same subject-matter as Specification 1,124,481 (see Division D1) but the claims relate to the seaming of two non-woven fabrics side-by-side, by forming the two narrower non-woven webs with a fibre content of at least 25% of a thermoplastic polymer fibre uniformly distributed therethrough and each feathered along one edge, overlapping the feathered edges and hotcalendering one surface of the combined web, thus splicing the two webs and simultaneously smoothing, compacting and densifying the fibre content and fusing the thermoplastic polymer at the surface into a loose matrix, while leaving the balance of the fibres in the web in a relatively expanded unbonded state. The physical properties are then substantially the same in the area of the splice as in the remainder of the web.

Filed: 1967-09-05
Abstract: 1,194,263. Freezing apparatus. CHEMETRON CORP. 5 Sept., 1967 [8 Sept., 1966], No. 40591/67. Heading F4H. Freezing apparatus comprises a housing 30 divided by partitions 58 into zones 50-57, removable covers 37 for closing the top of the housing, a conveyer 79 and means for supplying the vapour of a liquefied gas to one or more of the zones, the vapour being subsequently used for pre-cooling in the upstream zones. As shown, liquefied gas from pipe 91 passes through a vaporizer 90 extending through several of the zones and discharging into a freezing zone 51. Liquefied gas may additionally be supplied to zone 51 through atomizing nozzles 192, either or both of the gas supplies being controlled thermostatically. Partitions 58 are removable and include flap valves 110 to permit regulation of the amount of vapour passing to pre-cooling zones 52-57. A smaller quantity of vapour passes to zone 50 for postcooling via the openings in partitions 58 provided for passage of the conveyer belt. Each cover 37 has, on its underside, a housing 45 in which a fan 41 and its scroll casing 103 are disposed, the fan drawing vapour through an inlet 100 and discharging it to a distribution chamber 109 from which it passes through a perforated plate 107 on to and through the runs of the conveyer. The covers may be reversed (Fig. 10, not shown) so that the fan is directly above and draws vapour upwardly through the conveyer. Vapour traps 88 and 89 are provided at the ends of housing 30 and the ends of belt 79 are inclined in the traps. The discharge point 89<SP>1</SP> in trap 89 is higher than the inlet point 88<SP>1</SP> in trap 88 so as to assist in producing an upstream flow of vapour. In a modification (Fig. 12, not shown) separate charging and discharging belts are provided together with devices for transferring trays containing the product between these belts and the main conveyer. The fan housing and vapour distribution chamber may be separate from the cover 37 and hinged to the side walls of the main housing, the fan being driven by an air motor (Fig. 11, not shown).

Patent GB-410678-A (GB)
Abstract: 410,678. Television. WILSON, J. C., and BAIRD TELEVISION, Ltd., 58, Victoria Street, London. Oct. 18, 1933, No. 28842. [Class 40 (iii).] A rhythmic framing signal renders the synchronising appartus inoperative until the receiver has drifted into the correct phase. A synchronising frequency from an oscillator 6, Fig. 1, is transmitted through a commutator 3 during an interval between the last and first holes of a scanning disc 1. At the receiver all the signals are applied through an amplifier 15 to a Wehnelt cylinder 17, and the synchronising signals are applied across a selectively tuned circuit to an anodebend detector 16, which is normally kept quiescent by the voltage on its space-charge grid. At the end of each complete scanning the cathode-ray impinges on a conducting strip 23, and, if the ray is in synchronism, the synchronising frequency is applied across a tuned circuit 20 to the space-charge grid of the valve 16 and unblocks it. A synchronising signal is then supplied through an amplifier 21 to a saw-tooth generator 22. In a modification, using mechanical scanning at the receiver, the synchronising frequency is obtained through a striped reflecting prism 26, Fig. 2. At the receiver the synchronising signal is selectively amplified by a valve 32 and passed to an anode-bend detector 34. At synchronism the signal occurs when a relay 36 is short-circuited by a commutator 37, 40, and is applied to the coils 35 of a toothed-wheel corrector 39 described in Specification 336,655, [Class 40 (iii)]. Otherwise the signal operates the quick-make, slow-break relay 36 and the picture drifts. This continues until synchronism is obtained. Specification 320,639, [Glass 40 (iii)], also is referred to.
